Growth Conditions for Salvia dolichantha
Salvia dolichantha, also known as long-flowered sage, is a beautiful flowering plant that is native to the mountains of Mexico. It is a popular garden addition due to its striking long, tubular pink flowers and its hardiness.
Light Requirements
In order to grow healthy and produce vibrant flowers, Salvia dolichantha requires full sun to partial shade. In its native environment, it grows in sunny meadows with some shade. Therefore, it is best to provide it with at least 6 hours of direct sunlight daily. However, in hotter regions, it is recommended to protect the plant from too much sun exposure as this can cause its leaves to dry out and its flowers to wilt.
Temperature Requirements
This plant prefers moderate temperatures between 21°C to 26°C. In warmer temperatures, it is essential to provide adequate watering to prevent the soil from drying out. During winters, the plant can tolerate freezing temperatures as low as 14°C. However, it is recommended to protect the plant in colder regions as too much frost damage can harm the plant.
Soil Requirements
Like most plants, Salvia dolichantha prefers well-draining soil with good organic matter. It can adapt to different soil textures, including sandy, clay, or loamy soils. However, it is important to ensure that the soil is not waterlogged, as this can cause root rot, leading to the death of the plant. Adding compost or aged manure to the soil can improve the soil's fertility and the plant's growth. Furthermore, maintaining a pH range between 5.5-7 can prevent nutrient deficiencies and encourage healthy plant growth.
Overall, by following the recommended growth conditions, Salvia dolichantha can flourish and add beauty to any garden.
Cultivation Methods
Salvia dolichantha is a perennial herb that requires a sunny spot to grow well. Plant your Salvia dolichantha in well-draining soil, and ensure that the soil pH is between 7 and 7.5. These plants are drought-resistant, but they prefer regular watering. Therefore, planting your Salvia dolichantha in raised beds is a great way to ensure that the soil drains well.
Watering Needs
Salvia dolichantha is drought-tolerant, but it is recommended that you water it regularly during the growing season, especially when the soil is dry. Always ensure that the soil is well-draining, so water doesn't accumulate around the roots, causing root rot. It is vital to be careful not to overwater your Salvia dolichantha, as this can cause the roots to rot.
Fertilization
Salvia dolichantha does not require heavy fertilization, but it is recommended to add compost to beds at the beginning of each growing season. For a boost of nutrients, you can add a balanced, slow-release fertilizer two to three times per year. Remember, fertilize sparingly, as over-fertilizing can lead to a reduction of blooms in Salvia dolichantha.
Pruning
You should prune your Salvia dolichantha in the fall when blooming has stopped. Cut back up to one-third of the plant's height, removing all spent blooms and errant stems. This ensures that all new growth will have proper space and air circulation. During the growing season, removing any damaged or dead stems will encourage new growth and promote bushier plants that produce more flowers.
Propagation of Salvia dolichantha (Cory) Whitehouse
Salvia dolichantha (Cory) Whitehouse is a popular plant that can be propagated by various methods. This plant is native to Mexico and is commonly known as the Mexican sage or cherry sage. Propagation of Salvia dolichantha can be done through:
Seed propagation

Cuttings
Propagation by cuttings is also possible with Salvia dolichantha. Stem cuttings can be taken from the plant during the summer months and placed in a rooting hormone. The cuttings should then be placed in a well-draining soil mix and kept moist. Rooting should occur within 2-3 weeks and the new plant can be transplanted to a larger pot or into the ground.
Overall, propagation of Salvia dolichantha is relatively easy and can be done through a variety of methods including seed, division, and cuttings. With proper care, the newly propagated plants will thrive and provide an attractive addition to any garden.
